The TB5D1M has a built-in • 0.15 ns Output Skew Typical Between ± Pairs lightning protection circuit to absorb large transitions • Capable of Driving 50- Ω Loads on the transmission lines without destroying the • 5.0-V or 3.3-V Supply Operation device. When the circuit is powered down it loads the transmission line, because of the protection circuit. • TB5D1M Includes Surge Protection on Differential Outputs The TB5D2H device is a pin and functional replace- ment for the Agere systems BDG1A and BDGLA • TB5D2H No Line Loading When VCC = 0 quad differential drivers. Upon power down the • Third State Output Capability TB5D2H output circuit appears as an open circuit and • -40 °C to 85°C Operating Temp Range does not load the transmission line. • ESD Protection HBM > 3 kV and CDM > 2 kV Both drivers feature a 3-state output with a third-state • Available in Gull-Wing SOIC (JEDEC MS-013, level of less than 0.1 V. DW) and SOIC (D) Packages The packaging options available for these quad differential line drivers include a 16-pin SOIC gull-wing (DW) and a 16-pin SOIC (D) package. • Digital Data or Clock Transmission Over Both drivers are characterized for operation from Balanced Transmission Lines -40 °C to 85°C The logic inputs of this device include internal pull-up resistors of approximately 40 k Ω that are connected to VCC to ensure a logical high level input if the inputs are open circuited.
